Jez,

" dont know any reason to use a cpld in place of a few logic gates and then say its not overkill.My manager would sack me on the spot if i used a CPLD costing $5 where i could use a gal costing a tenth of that price. "

Funny, a quick search of Arrow's web site for GAL22V10 pulled up a bunch of non-stocked parts -- average price $4.00. XCR3032XLs (at Nu Horizons) tend to be $1.75 to $2.00. These are onesy-twosy quantities.

Overkill? Perhaps, depending on the design, but I like to pick the micro that has most of what I need already built in.
